Liner Plate of Milling Equipment Is Easy to Abrade

Liner plate is an essential part of ball mill. It is commonly made of metals and rubber. Generally speaking, liner plate has three main functions, including lifting steel balls or other grinding media in the barrel to a certain height, playing a grinding role and protecting the body of ball mill. However, liner plate is unfortunately of short service life. In this way, how can we prolong the service life of ball mill liner plate?

1. The impact of media material

The generally used crushing media materials include: various mine materials (manganese, copper, tungsten ore, chrome ore, etc.), various types of stone (limestone, granite, gneiss, basalt, gray rock, etc.) and industry coal used in power. The hardness of the media is the main basis that determines the liner plate wear, the higher hardness of the media and the shorter service life of the liner. On the contrary, if the media is with a lower hardness, the service life of the liner will be prolonged.

2. The impact of operating conditions

1) Eliminate defects not timely.

2) Adjusting undeservedly makes the ball mill running at a short position.

3. The impact of liner material

The main parameters affecting the anti-wear effect is matching of the two index of hardness and impacting toughness of liner material. If the liner plate has a higher hardness, which means it has a good wear resistance, and the two factors basically is a proportional relationship. The impacting energy depends on the size of the diameter of steel ball and grinding tube.

4. The impact of the ball mill's designing and manufacturing and the installing quality.

The performance of the lining plate generally include the following two: one is to protect the cylinder; another is that the liner plate rotates at a specific speed to raise the ball to the required height to achieve the desired effect.

The quality of the liner plate is also direct factor affecting the normal operation of the mill.
